ENABLE/DISABLE OPTIONS (E/N)

Statek offers three enable/disable options: E, T, and N.

Both the E-version and T-version have Tri-State outputs and

differ in whether the oscillator continues to run internally

when the output is put into the high Z state: it stops in the

E-version and continues to run in the T-version. So, the E-

version offers very low current consumption when the

oscillator is disabled and the T-version offers very fast output

recovery when the oscillator is re-enabled. The N-version

does not have PIN 1 connected internally and so has no

enable/disable capability. The following table summarizes

the three options.

Supply Voltage

1 = 1.8 V

2 = 2.5 V

3 = 3.0 V

4 = 3.3 V

5 = 5.0 V

7. The T-version is not available for all frequencies. Contact factory.
